Digital Pigeon can generate web friendly previews for a wide variety of media formats however there are some scenarios it can't handle:
- The preview system supports a maximum file size of 20GB, if a file is larger than 20GB we will not attempt to generate a preview for it. If you desire previews for very large files I'd suggest uploading a lower quality (preferably MP4) encoded version next to the original.
- If the preview system detects that it can't safely generate a preview, for example if a video has 'edit tracks' that manipulate sound, it will not generate a preview.
- If the system detects a encoding error (or something it believes to be an error) a preview will not be generated.
